A guide on the steamworks in Monster Hunter World: Iceborne. Included are the rewards obtained in the mini game.

What is the Steamworks?

The steamworks is a special facility that powers the Seliana research base in Hoarfrost Reach. You can help keep the steamworks running by collecting special materials that the facility uses as fuel. Doing so allows you to access a mini-game where you can obtain rare items that will be helpful on hunts.

The steamworks uses dragonvein shards, dragonvein coal, dragonvein coal chunks, and giant dragonvein coal as fuel. Each time you turn-in these materials, the steamworks engine’s drive gauge accumulates. The further you are in filling up the gauge, the higher the rarity of items you can obtain in the mini-game.

Completely filling up the steamworks engine’s gauge causes it to go into overdrive. This allows you to get a large amount of items in the mini-game.
